01? is it still under warrenty? just have to ask sometimes. they sell recharge kits at discount that come with a little guage. have used it and it is very simple to work. usually for a newer car, if it is low on freon (not cold, compressor cycles on and off alot) it has a leak, possibly the evap core. i say this because of past experiance, it usually is evap core here in lovely humid and hot fla. they also sell just the guage to check charge level. don`t over charge as this will cause it to not cool also, unlike r-12. let me know what you come up with...
